I'm doing an engine swap in my Triumph and have a flywheel question. Installing a 1973 TR6 engine in a GT6 and was wondering if anyone had used the lighter GT6 flywheel on their TR6? The TR6 flywheel is much heavier and thicker. Any ideas would be appreciated. email me at john70350 at msn.com if you have any ideas, thanks. John Johnson Columbus, Ohio
